Do the benefits of eating breakfast differ between boys and girls? Dr. Katharina Widenhorn-Mueller thinks so: the researcher reports that research into the effectiveness of a healthy breakfast for young people shows that boys report being in a fouler mood if they go without a morning meal but many girls do not. Well, we may not be kids anymore, but going without our morning meal and coffee can put us into a horrible mood. At the end of her report, Widenhorn-Mueller calls for more research into the gender differences in breakfast studies. We suggest she start here. [Reuters]
